Bus Crash At Piccadilly Circus

Reports are coming in that a bus has hit a woman at Piccadilly Circus, before crashing into railings badly enough to cause metal to fall into one of the tube entrances. The woman has been treated for an arm injury and taken to hospital. Two lanes on Regent Street are closed which is, fairly obviously, causing queues - so far all the way back to Hyde Park Corner according to TfL. BBC London has been sent a photo of the bus with its central doors badly mangled and a set of railings embedded underneath.
